Empirical results are presented employing data from thirteen manufacturing industries in eight OECD countries over the period of 1970 to 1991. We confirm, first, earlier findings that R&D expenditures are positively related to productivity levels, and estimate an elasticity of TFP with respect to own-industry R&D between 7% and 17%. Second, the receiving industry benefits also from other industries' technology investments, an effect which is at least in part due to trade in embodied technology. We find that the benefit derived from foreign R&D in the same industry is in the order of 50%-95% of the productivity effect of own R&D. Third, for domestic interindustry technology flows, the results strongly suggest that trade in goods is not all that matters for technology transmission. We estimate that domestic, outside-industry R&D is one-fifth to one-half as effective in raising" productivity as own-industry R&D for these industries. aHardcopy version available to institutional subscribers. aSystem requirements: Adobe [Acrobat] Reader required for PDF files. aMode of access: World Wide Web. 7aO3 - Innovation • Research and Development • Technological Change • Intellectual Property Rights2Journal of Economic Literature class. 7aO4 - Economic Growth and Aggregate Productivity2Journal of Economic Literature class.2 aNational Bureau of Economic Research. 0aWorking Paper Series (National Bureau of Economic Research)vno. w6113.4 uhttp://www.nber.org/papers/w611341uhttp://dx.doi.org/10.3386/w6113
